Here, I comment some relevant and selected papers which I consider they contribute somehow to the understanding of some of the perception and action topics.

In this paper we demonstrate that people can integrate early estimates of time to contact with late evidence to improve the precision of the catching. This happens mainly when the cues used for making early estimates are based on different information (e.g. elevation angle of a parabolic flight) than the late cues (e.g. expansion of the image object).

When we repeatedly point to objects with the unseen hand, our hand position drifts with respect to the targets. In this paper we demonstrate that this drift is an mainly a passive mechanism based on error accumulation. The system assumes the final position is mostly correct (based on priors) and do not make any correction until the discrepancy between the unseen hand and the target reaches a noticeable value.

Previous models (i.e. \(\eta\) and \(\tau\)) that tried to explain the profile of firing response neurons sensitive to impending collisions were mainly phenomenological and also include terms (i.e. exponentials) that are difficult to implement at the neural level. In this paper we propose a new framework which is neurophysiologically plausible and provides an unified account of different types of neural responses as well as psychophysical data.

The retinal image is ambiguous because depends on the object’s size and distance. Dominant models of time-to-contact (e.g. \(\tau\)-function) rely on optical variables only without resorting to physical variables. This paper shows that people very quickly assume a known physical size underlying the variability of the retinal image. Computations become simpler and people can time the initiation of the actions based on visual angle threshold. This paper provides a more general account of interceptive behaviour than López-Moliner, Field and Wann (2007).

This paper demonstrated for the very first time that prior knowledge of physical size of the approaching object affects the optical variable that is being used by the system. Subjects switched to using a rate of expansion threshold in the condition where physical size was known. The response then did not require combining visual angle and its rate of expansion. A posterior paper (commented above) generalizes the model that encapsulates physical size.


  • López-Moliner, J., Smeets, J. B. J., and Brenner, E. (2004). Components of motion perception revealed: two different after-effects from a single moving object. Vision Research, 44:2545–2549.

When looking at a normal moving object, there is only one perceived global motion. However, we know that locally there can be considerable ambiguity (the aperture problem). Does one adapt to all the local components of motion, including those that one does not perceive, or only to the perceived global motion? In this paper we nicely show that we adapt to components that are local and not perceived.
